CT images of the temporal bone of 29 patients without ear pathology and 30 patients with MD have been evaluated. The dimensions of the different structures of the inner ear were measured, using multiplanar reformations and three-dimensional reconstructions. In patients with MD, the length and the width of the vestibular aqueduct and the width of its external aperture were smaller, the size of the bony island of the lateral semicircular canal was smaller, and the diameter of lateral semicircular canal was bigger, compared with the values from the control group. We also found out that in patients with MD the distances between the bony labyrinth and the posterior petrous surface and between the posterior semicircular canal and the jugular fossa were smaller, than in normal subjects. In patients with MD, we found no significant differences in the majority of the values between affected and nonaffected ears. Our study confirms the hypothesis that congenital and developmental factors, such as hypoplastic vestibular aqueduct, dysplastic lateral semicircular canal and hypoplastic posterior part of the petrous bone, might play a role in pathogenesis of MD.</p></abstract><trans-abstract xml:lang="ru"><p>Целью нашей работы было определение размеров анатомических структур внутреннего уха в норме и выявление характера их изменений при болезни Меньера (БМ) с помощью компьютерной томографии (КТ). КТ височных костей была выполнена 29 отологически здоровым лицам и 30 пациентам с БМ. С помощью функций мультипланарной и трехмерной реконструкции были измерены размеры различных структур внутреннего уха. У пациентов с БМ длина и ширина водопровода преддверия, а также ширина его наружной апертуры были меньше, наружный полукружный канал был шире, а диаметр окружности наружного полукружного канала – меньше, чем у здоровых лиц. Также мы установили, что у пациентов с БМ расстояния между костным лабиринтом и задней гранью пирамиды и между задним полукружным каналом и яремной ямкой были меньше, чем в норме. Большинство показателей при БМ достоверно не различались на пораженной и непораженной сторонах. Наше исследование подтверждает гипотезу о вероятной роли в патогенезе БМ таких врожденных факторов, как гипоплазия водопровода преддверия, дисплазия наружного полукружного канала и гипоплазия задней части пирамиды височной кости.</p></trans-abstract><kwd-group xml:lang="en"><kwd>computed tomography</kwd><kwd>Meniere’s disease</kwd><kwd>temporal bone</kwd><kwd>inner ear</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>компьютерная томография</kwd><kwd>болезнь Меньера</kwd><kwd>височная кость</kwd><kwd>внутреннее ухо</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Терновой С.
